CARBURETER.

To aZZ whom it may concern;

Be it known that I, FRANKLIN l3. HAYS, a citizen of the United States,residing at Indianapolis, Marion county, and State of Indiana, haveinvented and discovered'certain new and useful Improvements inCarbureters, of which the following is a specification. v r

'My invention relates to carbureters and its object isto provide meanswhereby a" body of air is drawn through a body of hydrocar bon liquid sothat the air and liquid will be properly proportioned to provide ahighly volatile explosive mixture and the invention also aims to providea construction having means of a simple and effective characterv for Icontrolling the passage of the 'air through the carburetor andregulating its volume and that of the auxiliary air and the escapingvapor. j

= With these objects and others in view,'my invention is embodied inpreferable form in the construction and arrangement herein afterdescribed and illustrated in the accompanying drawings.

In these drawings, section through the carburetor; Fig. 2 a

horizontal section on the line 2 -2 of Fig. 1 gm l?1g.' 3, a horizontalsectlon on the line 3-3 of Fig. 1; Fig. 4, an outside view, partlybroken away of the hydrocarbon liquid receiving chamber andFig. 5, avertical section on the line 5'-5 of Fig. 1. 7

Referring to the drawings, 1 isan inlet adapted to communicate with asource of heated air and servingto admit a body of hot air to thecarbureter which constitutes the primary air supply. In the primary airinlet pipe are provided a series of cold air inlets 2 adapted to becontrolled by a valve 3 which consists of a circular ring havingopenings 4 adapted to register with and regulate the size of theopenings 2 and which is limited in a range ofmovement by means of setscrews5 secured to the inlet plate and extending through slots 6 in thering valve.

The inlet 1 leads to air chamber 7, the upper wall of which is formed bya partition 8 constituting part of the base of the carbureter and whichis provided with a series of openings 9 having beveled or curved seatsin which are adapted to be seated ball valves 10 which valves areadapted to be raised 7 Specification of Letters Patent.

chamber 18.

Figure 1 is a vertical yieldingly to their seats by means of a commonretaining member consisting of a cap 11 carried at the upper end ofavertical movable stem 12, the lower end of which is threaded andengages a sllding block 13 against the upper end of which block or nutbears a spring the upper end of which sprlng bears. against the lowerface of the cross partitionplate 8,'whereby the stem 12 and cap 11 arenormally pressed downwardly with a ylelding action seats to hold 1 theball valves to their seats with a yielding spring pressure. Above thevalves there .is

"provided'an annular chamber 14, formed by 1 and between the wall of theouter removable .sliell15 of the carbureter and the wall 16 of an innercylindrical .body.

The chamber 14 communicates by means of annularly disposed-spacedopeningsl'i with an annular The .chamber 18 communicates atits lower endby means of annularly disposed spacedaopenings 19 with an annularchamber 20 adapted tocontain wire gauze, the object of which istoeffectually break up the particles or" liquid hydrocarbon as the air isdrawn through the samefll The chamber 20 communicates'at its lower endwith a fuel chamber 21' having a names which fits against and is guidedsolely by the wallof the fuel chamber and which controls a lever 23hearing" against the upper;

open the opening 26 leading to the admission pipe 27, through whichgasolene or kerosene is adapted to be admitted.

The chamber 20 has an annularly arranged series of openings 28 in itsupper wall which lead into an auxiliary air receiving and mixing chamber29. This mixing chamber is provided with a circular rotatable body 30having openings 31 coiiperating with openings 32 formed in the wall ofthe carburetor to admit or exclude or regulate the admission of air intothe auxiliary air chamber for the purpose of admitting the necessaryquantity of diluting air according to atmospheric or other conditions.The auxiliary air valve formed by this ro tatable body is operated bymeans of a Worm or screw 33, the screw being carried by a shaft 34journaled in the wall of the carbureter. r

Above the auxillary alradmltting cham- 7 her is mounted a liquidcatching wire screen 85 which is adaptedto prevent large drops of liquidfuel from being carried to the ,outlet and to effect a final subdivisionof the liquid for the purpose of facilitating the intimate mixture andincreasing :the combustibility of the charge. 7

. Theroutlet 36 of the carbureter'is controlledby an oscillatory flatdisk valve 37 having segmental ports 38 adapted to register Withsimilarports inthe Wall 39 of the V carburetershell. A handle '40for'operatingzthisthrottle valve through the medium of a rack and pinionis provided. In the-operation of the carbureter the gasolene, keroseneor other liquid hydro-Y carbon fuel will be fedthroughv the inletpipe27to the fuel chamber 21 and when the fuel has risen in the latterchamber to the level of the openings 19, thefloat 22 will operate-tolift the lever 23 and: close the ber 14 andthence drawn down through theopening 517 into-2 the chamber 18 "where ,it

. 'willpick upth'e liquid hydrocarbon in the bottom of, said chamber andpass into the "chamber 20, whe're it will come in contact with 'a'further body of liquid hydrocarbon, the air thus. becoming 'carbureted.The

' liquid fuel is subjected tosuction and it will 7 Qbefdrawn up. againstthe wire gauze in chamber 20, thus breaking theliquid into fineparticles. .The carbureted air then passes through this. dividingv andsuspendf ing wire gauze and out into, the auxiliary air chamber; It willbe seen that the air.

drawn through the carbureter meets a body of liquid hydrocarbon. ofaifixed quantity dred' and sixteen.

which, is subject to suction and hence only that amount' of the liquidfuelwill be drawn forward to form a charge which the air is capable. ofabsorbing, thus preventing an excess of the liquid being impelledthrough the outlet by the mereforce ofthe induced draft of air as inthose types of carbureters in which the hydrocarbon fuel 7 is injectedinto arushing column of air;

The locatiouof-the fuel chamber Within the casing insures a supply ofliquid even when the car is running uphill at a steep incline and theform and arrangement of the float valve avoids the use of complicatedand expensive guiding constructions for the float. Having thus describedmy invention, WhatIclaimisr V j j 1. In a carbureter a float, a needlevalve operatedthereby,a float chamber, a plurality. of chambers oneofwhich contains wiregauze connected to saidifloat chamber so asto'receive liquid hydrocarbon fuel therefrom, means for passi ng airsuccessively through said plurality of chambers, an
